KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO – Ivanhoe Mines (TSX: IVN; OTCQX: IVPAF) Co-Chairs Robert Friedland and Yufeng “Miles” Sun announced today that underground development at the Kakula Copper Mine totalled 1,842 metres in August, bringing the cumulative total underground development completed to date to more than 20.6 kilometres – approximately 6.0 kilometres ahead of schedule.

The majority of the underground development headings at the Kakula Mine currently are traversing medium-grade sections of the orebody, with average grades ranging between 3% and 5% copper. A concentrated effort was made in August to complete the ledging development in the room-and-pillar section of the mine to accommodate critical infrastructure, such as piping and electrical cabling, for the mine’s permanent water-handling system.

The ledging development work will be completed early this month and will allow the mining teams to begin highly-productive stoping operations; however, the development work was in lower-grade ore and resulted in a temporary, modest decrease in overall stockpile grade in August and early September.

The stockpile grade is expected to improve, as planned, beginning this month as the majority of the working areas will transition to the higher-grade ore zones near the centre of the deposit that have copper grades approximately +5% to +8%.

The beneficial handover of the high-capacity ore conveyor system at the Kakula North declines was achieved at the end of July. All of the ore being mined in the northern portion of the Kakula Mine now is transported to surface via the conveyor system and placed on a blended, run-of-mine surface stockpile. The blended stockpile contains 483,000 tonnes grading an estimated 3.76% copper; comprised of 116,000 tonnes of high-grade ore grading 6.08% copper and 367,000 tonnes of medium-grade ore grading 3.02% copper.

Two additional, pre-production ore stockpiles are located at the Kakula South decline (approximately 121,000 tonnes grading 2.36% copper) and the Kansoko decline (approximately 68,000 tonnes grading 2.21% copper). More than 109,000 tonnes of ore was added to the project’s pre-production stockpiles in August.

Surface conveyor systems to transport the ore from the Kakula North stockpile to the processing plant are under construction.

First copper production expected in less than a year

Initial production at the Kakula Mine is scheduled for Q3 2021. Kakula is projected to be the world’s highest-grade major copper mine, with an initial mining rate of 3.8 million tonnes per annum (Mtpa) at an estimated average feed grade well in excess of 6% copper over the first five years of operation.

The Kakula Mine will have one of the most favourable environmental footprints of any tier-one copper mine anywhere in the world. The mine will be powered by clean, renewable hydroelectricity and be among the world's lowest greenhouse gas emitters per unit of copper produced. Kakula also will have a relatively small surface footprint as approximately 55% of the mine’s tailings will be pumped back into underground workings.

The Kamoa-Kakula Copper Project is a joint venture between Ivanhoe Mines (39.6%), Zijin Mining Group (39.6%), Crystal River Global Limited (0.8%) and the DRC government (20%).

“Together with our joint-venture partners, we look forward to sharing the independently verified engineering and economic studies on September 8th that will showcase why Kamoa-Kakula is, without question, the world’s best new copper project,” said Mr. Friedland. “Kamoa-Kakula is unique as it combines ultra-high-copper grades with thick, shallow, flat-lying ore zones, providing the economies of scale and low mining costs of large, open-pit mining operations, but without the visual environmental impact associated with open-pit mining.”

“We also plan to soon announce the appointment of a leading environmental consulting firm to audit Kamoa-Kakula’s greenhouse gas intensity metrics, providing Environmental, Social and Governance investors with independent and transparent verification of the project’s achievements towards our goal of producing the world’s greenest copper,” Mr. Friedland added.

Kakula Mine development progressing towards zone of +8% copper in centre of deposit

Underground development of the Kakula Mine – the first of multiple, near-surface copper deposits that are planned to be put into production on the 400-square-kilometre Kamoa-Kakula mining licence – is now significantly ahead of schedule. Mine access drives 1 and 2 (interconnected, parallel tunnels that will provide access to ore zones) being driven from the Kakula northern declines continue to advance towards the southern portion of the orebody.

Development of the eastern perimeter drives also is well advanced as are the access drives to the room-and-pillar mining area. Development of twin access drives being driven from Kakula’s southern portal has reached the +5% copper mining zone, with mining crews working to establish the connection of these drives with mine access drives 1 and 2 from the northern side of the orebody. The northern and southern access drives are expected to join in November 2020, which will be a major milestone in the development of the Kakula orebody.

Once the northern and southern access drives are connected, the majority of mining activities will focus on the initial drift-and-fill mining blocks in the centre of the Kakula deposit, where the average grade is higher than 8% copper. Drift-and-fill stoping is a highly-efficient form of underground mechanized mining and will allow the operation to efficiently recover significantly more tonnes from the orebody.

Underground mining with two mining crews also is taking place at the Kansoko Mine, located at the Kamoa deposit, approximately 10 kilometres north of the Kakula Mine.

The construction of Kakula’s second permanent underground water-handling system is nearing completion with the first of four pump trains commissioned in early August; the second pump train was commissioned in the last week of August. The new system adds 800 litres per second of underground pumping capacity, bringing the total installed capacity to 1,400 litres per second. Two additional underground water dams are under construction; one at bottom of the southern declines, and one along the north eastern perimeter drifts.

Ivanhoe plans to issue the independent definitive feasibility study for the development of the 6 Mtpa Kakula Mine on September 8, 2020. The company also will issue a pre-feasibility study, including mining 1.6 Mtpa from the Kansoko Mine, to take full advantage of an expanded plant capacity of 7.6 Mtpa at Kakula. In addition, the company will issue an updated, expanded preliminary economic assessment for the overall development plan of up to 19 Mtpa for all of the copper discoveries made to date at the Kamoa-Kakula Project.

Construction on the processing plant and other surface infrastructure rapidly progressing

Construction of Kakula’s initial, 3.8-Mtpa concentrator plant is progressing well, with approximately 20,000 cubic metres of concrete being poured to date. Concrete bases for the ball mills, flotation plant and the concentrate thickener have been partially handed over to the mechanical contractor to commence installation work, and mechanical erection and installation is underway in most of the plant areas. Structural steel fabrication is complete with more than half of the approximately 6,000 tonnes of structural steel already delivered to site. Fabrication of platework and piping is progressing according to schedule with the first deliveries already on site; platework installation has started.

Total steel prefabricated or installed is approximately 2,000 tonnes. All floor and sidewall plates for the concentrate thickener now are in position, and welding is 40% complete.

Installation of the tailings thickener has commenced, with the centre column being placed in position and welding of the floor plates underway. Pre-assembly of the high-pressure grinding rolls feed bin #1 conveyor has started. Both secondary crushers have been assembled and placed in position. Installation of the first ball mill shell has been completed.

All 21 oversized truck loads of equipment for the processing plant’s primary ball mill − measuring 9.75 metres (32 feet) long and 6.1 metres (20 feet) in diameter – have arrived on site. The final shipments of the ball mill components are scheduled to arrive at site this month, which will be the final deliveries of long-lead plant equipment.

Beijing-based CITIC Construction is building Kakula’s first-phase, backfill paste plant. The backfill plant will be used to blend tailings from the processing plant with cement to produce paste backfill. The backfill will be pumped back into the mine and used to help support mined-out areas. Approximately 55% of the mine’s tailings will be sent back underground, significantly reducing the surface tailings storage.

Construction of the tailings dam has commenced and is progressing well; with the aim to complete most of the earthworks before the rainy season starts in November.

Discussions underway for the marketing of Kakula’s copper concentrates

Kamoa-Kakula is in detailed discussions with a number of parties with respect to the marketing and smelting of its copper concentrates. Kakula is expected to produce an extremely high-grade and clean copper concentrate that will be highly coveted by copper smelters around the world. Metallurgical test work indicates that the Kakula concentrates contain extremely low arsenic levels by world standards – approximately 0.01%.

Clean, sustainable hydro-electric power for Kamoa-Kakula

Construction activities at the Mwadingusha hydro-electric power plant, where all six turbines are being replaced, is progressing well; as is the associated 220-kilovolt (kV) infrastructure to supply Kamoa-Kakula with clean hydro-power. The mine is scheduled to be energized with permanent 220kV hydro-generated power in early 2021, well in time for first copper production.

The temporary construction power supply for the Kakula Mine was recently upgraded, including the commissioning of six 2-megawatt (MW) generators to provide back-up power, and the installation of an 18 MW/120-kilovolt (kV) mobile substation to increase the capacity of grid power available at the mine. This will provide sufficient power until the main 220kV power supply is energized. An additional six new 2MW generators have arrived at the port of Durban from China, and are en route to site. The twelve generators will supply the full back-up power requirements for the mine.

Construction of the 220kV supply infrastructure is in progress, including a new 220kV distribution sub-station for the power utility (SNEL); a new 35-kilometre, 220kV power line; and a consumer substation at Kakula with two 80 MW/220kV transformers.

Installing a new alternator in the Mwadingusha hydro-electric power plant. Mwadingusha will soon be delivering 72 MW of clean, sustainable hydroelectricity to the national grid.

Kamoa-Kakula’s COVID-19 readiness initiatives focused on risk mitigation

In accordance with new health guidelines from the DRC government, and in line with the country’s lifting of restrictions, Kamoa-Kakula lowered its quarantine and lockdown measures from level 3 to level 2 on July 27th. The mine’s Congolese workforce have gone back to normal rotation. Rigorous testing, physical distancing, wearing face masks, frequent hand washing and contact tracing measures are still in place to protect the safety and health of the workforce and community members. All expatriate employees are still required to quarantine for two weeks upon arrival at Kamoa-Kakula.

The project has established a COVID-19 isolation facility at the Kamoa camp. Any potential symptomatic patients are moved to this facility, where they will be isolated, tested and treated. Once the patient has recovered and is deemed no longer infectious, they can return to work only after an additional quarantine period determined by the project’s medical staff in dedicated quarantine.

As the pandemic evolves, the medical team at Kamoa-Kakula is purposefully reviewing and updating its risk mitigation protocols. The project’s preventative measures are at the highest international standards and, if there was a case internally, the risk of spreading or cross-contamination is very low.

刚果民主共和国科卢韦齐 — 艾芬豪矿业 (TSX: IVN; OTCQX:IVPAF) 联席董事长罗伯特·弗里兰德 (Robert Friedland) 与孙玉峰 (Miles Sun) 今天宣布,卡库拉铜矿的地下开发持续快速推进,于8月份共掘进1,842米,迄今为止已经完成了20.6公里以上的地下开拓工程,超过既定目标约6.0公里。

目前,卡库拉矿山的大多数开拓巷道横贯中品位的矿段,其平均铜品位在3%5%之间。项目于8月份着重在矿山房柱式采矿区建设壁架,以容纳矿山永久水处理系统的管道和电缆等重要基础设施。

壁架工程将于本月初完成,使采掘班组可以尽快展开高效的采矿作业。然而,工程位置的矿石品位较低,因此8月份至9月初的矿堆品位将会暂时稍为下跌。

大多数工作区将于本月过渡到矿床中心附近的高品位矿区,铜品位约为+5%至+8%。因此,矿堆的品位将按计划进度而有所提升。

卡库拉北部斜坡道的高负载矿石输送系统,已于7月底正式运行。目前,所有在卡库拉矿山北部开采的矿石将经由输送系统运送到地表的混合矿堆。混合堆场目前已储备矿石量约483,000吨,铜品位约3.76%,其中包括116,000吨的高品位矿石 (铜品位6.08%) 以及367,000吨的中品位矿石 (铜品位3.02%)

此外,项目还有两个额外的投产前矿堆位于卡库拉南部斜坡道 (121,000吨矿石,铜品位2.36%) Kansoko斜坡道 (68,000吨矿石,铜品位2.21%)。于8月份,项目的投产前矿堆已增加超过109,000吨矿石。

地表输送系统的施工正在进行中,将从卡库拉北部的矿堆的矿石运送到选矿厂。

首批铜精矿生产将于一年内实现

卡库拉矿山计划于2021年第三季度实现首批精矿生产,预期将会成为全球品位最高的大型铜矿,初始年处理矿量为380万吨,估计投产后头5年的平均给矿铜品位达6%以上。

相比任何顶级铜矿,卡库拉将会是具有最佳环境足迹的矿山之一。它将使用清洁、可再生的水电,并将成为全球每单位铜的温室气体排放量最低的矿山之一。矿山约55%的尾矿将被泵送回地下,卡库拉的地表足迹因此相对较小。

卡莫阿-卡库拉铜矿项目是艾芬豪矿业(占股39.6%)、紫金矿业集团(占股39.6%)、晶河全球(占股0.8%) 及刚果政府(占股20%) 的合资项目。

弗里兰德先生说﹕我们期待于98日与我们的合资伙伴一起向外界公布卡莫阿-卡库拉项目的独立核实的工程和经济研究报告,帮助大家了解卡莫阿-卡库拉为何会是全球最为优秀的新建铜矿项目。卡莫阿-卡库拉是独一无二的,拥有厚大、接近地表和平伏的矿体和超高的铜品位,适合进行大型的露天采矿作业,易于实现规模效益和低采矿成本,且不会造成像露天采矿一样的、可见的环境影响。

弗里兰德先生补充说﹕我们还计划马上宣布聘请一家领先环保顾问公司的消息,该公司将负责审查卡莫阿-卡库拉将会产生的温室气体强度指标,向关切环境、社会责任和企业治理的投资者提供独立和透明的调研结论,以证明我们为达到生产世界上最环保铜金属之一目标所做出的成绩。

卡库拉南面斜坡道的中品位堆矿,目前储备矿石量约121,000吨,铜品位2.36%

Kansoko斜坡道的中品位堆矿,目前储备矿石量约68,000吨,铜品位2.21%

卡库拉矿山持续推进开发,将到达矿床中心铜品位8%以上的矿段

卡库拉矿山是卡莫阿-卡库拉项目涵盖的400平方公里开采许可范围内多个近地表铜矿的首产矿山,地下开采工程持续超计划高效推进。矿山的1号和2号运输通道正从卡库拉北面斜坡道朝着矿体的南部掘进,施工进展顺利。两条运输通道是相互连接的平行通道,将连通至开采矿段。

同时,东部外围通道和房柱式采矿区的工程的进展也十分理想。两条运输通道已从卡库拉南部矿坑口到达铜品位高于5%的开采矿段,采掘班组正在将这两条通道与矿体北部的1号和2号运输通道连接。南北运输通道预计于202011月连接完成,将会是卡库拉矿体开拓工程的重要里程碑。

南北运输通道连接后,大多数的采矿活动将会集中在卡库拉矿床中心的首个分层充填采矿区,该矿区的平均铜品位达8%以上。分层充填采矿是一种高效的机械式地下采矿法,可有效地大大提升从矿体采掘的矿石量。

位于卡库拉矿山以北约10公里,卡莫阿矿区范围内的Kansoko矿山,目前正有两队采掘班组在进行地下采矿工程。

卡库拉第二永久地下水处理系统的施工将近完成。系统设有4个泵组,第1个泵组已于8月初运行,而第2个泵组也于8月最后一个星期开始运行。新系统将地下泵流量提升每秒800公升,使总装置容量达到每秒1,400公升。目前正在加建两个地下水坝,一个位于南面斜坡道的底部,另一个则沿着东北面的周边平巷建造。

艾芬豪计划于202098日发布卡库拉矿山年处理矿量600万吨开发工程的独立最终可行性研究报告。同时,公司将会发布包含Kansoko矿山 (年开采矿量160万吨) 的预可行性研究报告,以充分利用卡库拉矿区将扩建至年处理矿量760万吨的选厂产能。此外,公司还将发布卡莫阿-卡库拉项目至今所有铜矿资源的整体开发计划(年处理矿量可达1,900万吨) 的更新和扩充的初步经济评估报告。

输送带工Martin Nkulu正在监控高品位铜矿石经卡库拉北面斜坡道的输送系统运送到地表,该输送系统每小时可输送2,000吨矿石。

一台装载着铜矿石的卡车驶向卡库拉南面的斜坡道。其中一条南部运输通道已进入铜品位高于5%的开采矿段,另一条也快将到达。南北运输通道预计于11月连接完成。

选矿厂和其他地表基础设施的施工快速推进

卡库拉年处理矿量 380 万吨选矿厂的施工进展顺利,至今已灌入20,000立方米以上的混凝土。球磨机、浮选厂和精矿浓密机的混凝土底座部分已交给机械承包商开始进行安装,且大部分厂房区域正在搭建钢架。约有6,000吨的钢结构已制造完成,其中一半以上的钢结构已运抵矿场。板金和管道的制造正按计划进行中,首批货运已抵达矿场,并已开始安装板金。

预制和已安装的钢材合共约有2,000吨。目前,精矿浓密机的所有底板和侧墙板已确定位置,且已完成40%的焊接工作。

尾矿浓密机已开始进行安装,中柱已放到指定位置,并正进行底板的焊接。高压辊磨机矿仓的1号输送系统已开始预先组装。两台二段破碎机都已组装并放到指定位置。第一台球磨机的外壳已完成安装。

装载着选矿厂主要球磨机(9.75/32英尺、直径6.1/20英尺) 设备的21辆大型卡车已运抵矿场。最后一批的球磨机组件计划于本月运抵矿场,这将会是最后一批需要运输的长周期设备。

北京的中信建设正在兴建卡库拉第一期的回填厂。回填厂将选矿厂的尾矿与水泥混合制造回填浆。回填浆将会泵回矿山用作填充采空区。矿山约55%的尾矿将被泵送回地下,大大减少地表的尾矿量。

关于卡库拉铜精矿销售方案的讨论正在进行中

目前,卡莫阿-卡库拉正与多方就铜精矿的销售和冶炼方案进行详细讨论。卡库拉将会生产极高品位的清洁铜精矿,将会是世界各地铜冶炼厂渴求的高质量产品。冶金测试结果显示,按全球标准,卡库拉精矿的含砷量极低,约为0.01%

卡莫阿-卡库拉项目的清洁、可再生水电

Mwadingusha 水电厂的施工进度可观,当前正在进行全部6台涡轮机的更换。同时,220千伏的相关基础设施工程进展顺利,将为卡莫阿-卡库拉矿山提供清洁的水电能源供给。计划于2021年初达到220千伏永久性水力发电能力,其时间表预计将与矿山的首批铜精矿生产进度完美匹配。

卡库拉矿山的临时建设电源最近已进行升级,包括已调试62兆瓦发电机用作后备电源,并已安装18兆瓦/ 120千伏的移动变电站,以增加矿山可用的电网容量。这将在220千伏主要电力投入使用前提供足够的电力。另外6台新的2兆瓦发电机已从中国抵达南非德班港口,目前正在运送途中。这12台发电机将为矿山提供足够的后备电源供给。

220千伏供电基础设施的建设正在进行中,包括﹕用于刚果国家电力公司(SNEL) 220千伏新配电变电站、一条35公里长的220千伏新输电线,以及一座位于卡库拉的用户变电站 (设有两个80兆瓦 / 220千伏的变压器)

卡莫阿-卡库拉项目的COVID-19应对举措以减低风险为重点

根据刚果政府的新卫生指引,并配合该国解除的部分限制,卡莫阿-卡库拉于727日将其检疫和封锁隔离措施从第3级降低到第2级。矿山的刚果员工已经恢复正常的换班安排。矿山继续实施防疫措施如严格测试、保持距离、配戴口罩、经常洗手和接触者追踪调查等,以保护员工和社区成员的安全和健康。所有外籍员工抵达卡莫阿-卡库拉后仍需进行两个星期的检疫隔离。

项目已在卡莫阿营地设有COVID-19隔离设施。任何疑似或出现病症的人员都将会安排到该设施,进行隔离、检测和治疗。患者康复且不再具传染性后,只能在项目医务人员订立的额外隔离观察期结束后才可返回工作岗位。

随着疫情的变化,卡莫阿-卡库拉的医疗队伍正积极审阅和更新其疫情防控方案。项目的防疫措施符合最高国际标准,即使内部出现感染病例,传播或交叉感染的风险也非常低。
